• A spring-loaded latch on the front of the base that fits into a security slot on the bottom of the computer secures the computer to the docking control base. Not all Dell computers have the security slot. • A secured media-bay eject button that blocks removal of media bay devices. • An immobilized catch latch to deter unauthorized computer removal. 22 Dell Latitude C/Port II APR System Information Guide Securing the C/Port II APR Use one of the following methods to secure the docking device: • Use a padlock alone or a padlock and looped security cable with the padlock slot (see “Docking Control Base Controls and Indicators”) on the docking device. A padlock alone blocks the eject lever and makes it difficult to detach the computer from the docking device. A security cable looped around a stationary object and used in conjunction with the padlock can help prevent the unauthorized movement of the computer and the C/Port II APR. • Attach a commercially available antitheft device to the security lock slot (see “Docking Control Base Controls and Indicators”) on the docking device. Antitheft devices usually include a segment of metal-stranded cable with an attached locking device and associated key. Dell recommends that you use a Kensington lock. For instructions on installing this kind of antitheft device, see the documentation that accompanied the device. Dell Diagnostics The Dell Diagnostics that came with your Dell Latitude computer includes tests that help you troubleshoot the controllers in your docking device. The subtests in the Network Interface test group of the Dell Diagnostics verify the basic operation of the network controller in the docking device. They test the controller's internal functions, including read and write access to its registers and internal transmit and receive (loopback) capability. The subtests in the Serial/Infrared Ports test group check the docking device's interface with external devices (such as a serial mouse or a printer). The subtests in this test group are not intended as a diagnostic test for the external device itself. Dell Latitude C/Port II APR System Information Guide | support.dell.com The subtests in the USB test group check the docking device's interface with external devices (such as a mouse). The subtests in this test group are not intended as a diagnostic test for the external device itself. For complete instructions on using the Dell Diagnostics, see your computer's User's Guide.

Radio communications services include but are not limited to AM/FM commercial broadcast, television, cellular services, radar, air-traffic control, pager, and Personal Communication Services (PCS). These licensed services, along with unintentional radiators such as digital devices, including computers, contribute to the electromagnetic environment. Dell Latitude C/Port II APR System Information Guide | support.dell.com Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly together in the electronic environment. While this computer has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference with radio communications services, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures: • Reorient the receiving antenna. • Relocate the comp...
